(54) APPARATUSES AND METHODS FOR ACOUSTIC NOISE CANCELLING


(57) The present disclosure relates to concepts of acoustic noise cancelling. A noise cancelling apparatus contains a propulsion component configured to autonomously move the noise cancelling apparatus, and circuitry. The circuitry is configured to determine a position of an acoustic source, to determine a position of an acoustic receiver, and, depending on the detected positions of the acoustic source and the acoustic receiver, to control the propulsion component to navigate the noise cancelling apparatus to a target position to at least partly cancel an acoustic signal from the acoustic source at the position of the acoustic receiver.
